Published: October 2008

A new cobalt-catalysed reductive coupling of aryl halides with benzyl chlorides is reported; a variety of diarylmethanes can be prepared in good to excellent yields under mild reaction conditions using CoBr(2) as catalyst and Zn dust; this new cobalt-catalysed coupling represents a practical and interesting alternative to previously known methods for the synthesis diarylmethanes.

Chlorination is a widely used strategy at the industrial level. Chlorinated products represent indispensable building blocks in synthetic chemistry. Here, we report the synthesis of benzyl chlorides and α-chloro alkyl arenes, mediated by visible light, starting from variously substituted toluenes and -dichloroacetamide as a chlorinating reagent.

Imidates are versatile synthetic intermediates that contain ambiphilic reactivity, making them valuable pharmaceutically relevant synthons. Despite their extensive utility, imidates are typically generated in situ rather than isolated due to their inherent instability. This report details a systematic study that led to the discovery of an isolable imidate hydrogen chloride (HCl) salt that exhibits high tolerance to hydrolysis, thereby improving process control and facilitating downstream transformations.

Phosphorus (P) fertilizer is an essential component of our food system with the majority of all mined P rock processed to make mineral fertilizers. Globally however P rock stocks are declining-both in quality and quantity-with poor P management creating a linear economic system where P is mined, globally redistributed into products and eventually discharged into the environment leading to eutrophication. To enable establishment of a circular P economy, whereby P can be recovered from waste for its industrial reuse, requires the development of effective P recovery technologies.

The objective of this study was to produce new and renewable bio-based plasticizers from used soybean cooking oil (USCO). First, USCO was completely converted into free fatty acids (FFAs) using lipase from Candida rugosa. Next, these FFAs were enzymatically esterified with benzyl alcohol in solvent-free systems.

In this paper, two triazine ring-containing quaternary ammonium salt Gemini surfactants (C-2-C and C-2-C) were synthesized. The minimum inhibitory concentrations against sulfate-reducing bacteria (SRB) of C-2-C, C-2-C and dodecyl dimethyl benzyl ammonium chloride (1227) were determined using the double-dilution method. The performance of C-2-C and C-2-C in inhibiting carbon steel corrosion in the presence of SRB was examined, with 1227 serving as a control sample.
